HENRY O. CHENEY, OF HOPKINTON, ASSIGNOR OF ONE-THIRD TO CHARLES F. PIKE,OF WOODVILLE, MASSACHUSETTS.

PLOW.

SPECIFICATION forming part of Letters Patent No; 502,877, dated August8, 1893.

Application filed October 14, 1892.

To all whom it may concern,-

Be it known that I, HENRY O. CHENEY, of Hopkinton, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Plows, of which the following is a specification.

This invention has special relation to that class or kind of plows whichis adapted to have the furrow-turning means reversed, so that the plowmay be traversed back and forth, turning all the furrows in onedirection, and avoiding so called open furrows.

It is the object of the invention to provide such improvements in swivelor reversible plows as will enable the same to be quickly and easilyreversed, be readily taken to and from the field, to be easily turned atthe end of a furrow, to be made to at once meet an emergency occasionedby the breakage of a point or share, and to possess other advantages andovercome other objections of greater or less importance, as will morefully appear hereinafter.

To these ends the invention consists of the improvements which I willnow proceed to describe and claim, reference being hadto the annexeddrawings and to the letters marked thereon, the same letters designatingthe same parts or features, as the case may be, wherever they occur.

Of the drawings-Figure 1, is a side view, partially in section, anddrawn to an enlarged scale of the principal parts of the improved plowconstituting the invention, the land-side facing the observer. Fig. 2,is an opposite side view of the improved plow, the representation beingupon a reduced scale. Fig. 3, is a perspective view of the principalparts of the improvement, from the mold-board side. Fig. 4, is a similarview from the landside. Fig. 5, is a top plan view of the improved plow.Fig. 6,is a perspective view of the latch for holding the point andmold- Fig. 7, is 'a'sectional view taken on the line 7, f Fig. 1. Fig. 8is a sectional view taken on the line 8 8 of Fig. 1.

In the drawings, a designates the beam; 1),

the handles; 0, the rounds connecting and bracing the handles; and d,the frame with sea N5. 448,829. (NomodeL) which the beam, handles andother parts of the plow are rigidly connected.

e, designates the mold-board which is made double, and which is at itscenter swiveled upon a bolt f, supported at its ends in the beam andplow frame, and extending at an angle of about forty-five degrees to thebeam, so that when one of the double parts is in operative position theother will extend upon the same side of the beam out of the 'Way. Eachof the double parts is provided with a removable point or share g, asusual.

h, designates the land-sides, one being connected with each mold-board,so that the plow is equipped with double complete furrowturning means.

In the bottom of the frame d, at the heel of the land-side there isawheel 2', arranged between two plates j, bolted to the frame. See Fig.7.. Bosses or journal studs k, may be cast or formed integral with thewheel, and arranged to operate in depressions or recesses formed on theinner faces of the plate j, as shown... With these means, by bearingdown slightly on the handles, the whole weight of the plow may bebrought upon the wheel 1', so that it may be taken to and from the fieldor from other place to place with. the greatest ease and readiness.Besides this the wheel at the land-side affords means for the readyturning of the plow, and for effecting the reversal of thefurrow-turning devices. V .Z, designates a latch-bolt orbar arranged toslide m the frame. above the .wheel 11, and at substantially a rightangleto the boltf, which bar is notched at its lower end as at m (seeFig. 8), so as to engage a catch a, provided on the inner face of eachland-side, at the heel thereof, the sides of the lower end of thelatchbolt being beveled, asshown, so as to permit the bolt to snapoverthe catch when the latter is brought thereagaihst with sufficientforce.

0, is a springsecured to the frame and connected with the latch-bolt insuch manner as to operate with a tendency of forcing the said boltdownward.

p is a lever fulcrumed inthe frame and provided on its outer end with aplate or other means which will permit the toeof the foot of the plowmanto be placed thereon in order to depress the said end of the lever andraise its inner end and the latch-bolt with which the inner end of thesaid lever is connected.

q, is a double latch pivoted upon the frame and having its outer endconnected through the medium of a pitman '2", with theinner end of thelever 17, and upper end of the latchbolt 1. The latches q, are beveledon their outer ends, and are so arranged as that when the plow isreversed, the land-side of the part thrown out of action, will at itsupper edge engage the beveled part of the latch, depress the same, andallow the offset part of the latch to catch on the inner side of thelandside, and with the latch-bolt engaging the land-side of the otherpart of the plow, hold the same in operative position. The upper end ofthe bolt fis provided with a pinion s or it may be a segmental gearwhich is engaged by a toothed segment 15 formed on the lower end of alever to pivoted upon the beam of the plow. The upper end of the saidlever 11. is provided with a handle which rests upon the upper round 0which may be offset or notched near its ends so that the handle maybeheld in place when moved into on gagement with the said offsets ornotches. Supposing the plowman to have reached the end of a furrow, andthat it is desired to reverse the plow, he may place the toe of his booton the outer end of the lever 13 raise the latch-bolt Z and lower thelatch q so as to release the land-side and mold-boards, and then takinghold of the handle of the lever to he may shift said lever to theopposite side on the round 0, reversing the plow through the medium ofthe bolt f, its gear 8 and the segment 6, and when the parts swingaround into place they will be automatically engaged by the latch-boltand latch and held in place as has already been described. By pressingdown slightly on the handles the plow can be balanced on the wheel atthe heel of the landside and the plow reversed and turned with greatease and convenience.

It will be noted further that the invention affords a swivel orreversible plow which may be made light so as to be employed with onehorse; that each plow, by being provided with a land side can be veryeasily held and guided; that the mold-board can be formed so as to giveany desired turn to the furrowslice; that in case of breakage of a pointor share the work may be immediately continued by the use of the otherplow; and that the construction, in view of the functions performed, issimple, and not liable to get out of order.

I claim 1. A reversible plow comprising in its construction a beam,handles, and a frame all rigidly secured together; a rotatable boltsupported by the frame and beam; a double moldboard fixed on said bolt;a pinion fixed on the bolt; and a lever fulcrumed on the beam and havinga segment at its end in mesh with said pinion, the opposite end of saidlever arranged to be vibratedbetween the handles of the plow, wherebythe mold-board is reversed in the manner described.

2. The combination, with the double furrow turning means, each providedwith a land-side having a catch n, of a spring-pressed latchbolt or bar,notched at its lower end to engage the said catch, and beveled oppositeits notched point, as described.

' 3. The combination, with the double furrow turning means, eachprovided with a land-side having-a catch a, of a spring-pressedlatchbolt or bar, notched at its lower end to engage the said catch, andbeveled opposite its notched point, alever fulcru med on the frame,engaged at its inner end with said bolt and adapted at its outer end tohave the foot of the plowman placed thereon to depress the said outerend and raise the inner end, as described.

as. The combination, with the double furrow turning means, of the platesj bolted to the frame at the heel of the land-side and provided withdepressions, and the wheel provided with bosses arranged in saiddepressions between the said plates, as described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 21st day of September, A. D.1892.

HENRY O. CHENEY.
